Adding dashboard widgets
Here is a simple dashboard widget:
/** * Add a new dashboard widget. */ function wpdocs_add_dashboard_widgets() { wp_add_dashboard_widget( 'dashboard_widget', 'Example Dashboard Widget', 'dashboard_widget_function' ); } add_action( 'wp_dashboard_setup', 'wpdocs_add_dashboard_widgets' ); /** * Output the contents of the dashboard widget */ function dashboard_widget_function( $post, $callback_args ) { esc_html_e( "Hello World, this is my first Dashboard Widget!", "textdomain" ); }Expand full source codeCollapse full source code
Running dashboard widgets
To run the function use this code:
Adding widgets onto the side
The function doesn’t allow you to choose where you want your widget to go and will automatically add it to the “core” which is the left side. However you are able to get it on the right side very easily.
You can use the
add_meta_box()function instead ofwp_add_dashboard_widget. Simply specify ‘dashboard’ in place of the$post_type. For example:As noted in comment #714,
wp_add_dashboard_widget()does not offer a great deal of flexibility to position a widget on the dashboard; however, it is possible to add a widget to a specific dashboard column relying onadd_meta_box()and its$contextparameter.The example below removes all core dashboard widgets and adds a custom one to the third dashboard column (tested ltr only). It looks odd, but it proves the point. 🙃
<?php namespace Exampledashboard; add_action( 'wp_dashboard_setup', __NAMESPACE__ . 'wp_dashboard_setup' ); /** * Remove core widhets and add widget to Dashboard in third column. * @see https://developer.wordpress.org/reference/functions/add_meta_box/ */ function wp_dashboard_setup() { // Remove Welcome panel. remove_action( 'welcome_panel', 'wp_welcome_panel' ); // Remove all Dashboard widgets. global $wp_meta_boxes; unset( $wp_meta_boxes['dashboard'] ); // Add custom dashbboard widget. add_meta_box( 'dashboard_widget_example', __( 'Example Widget', 'example-text-domain' ), __NAMESPACE__ . 'render_example_widget', 'dashboard', 'column3', // $context: 'advanced', 'normal', 'side', 'column3', 'column4' 'high', // $priority: 'high', 'core', 'default', 'low' ); } /** * Render widget. */ function render_example_widget() { ?> <p>Do something.</p> <?php }Expand full source codeCollapse full source code
